Union leaders are due to meet Carwyn Jones on Monday to discuss the way forward.

But he has already given a firm warning about the prospects of reopening the export markets.

He has said that if livestock markets are allowed to start trading prematurely, Wales may not be able to export for five years.

"If we open the marts early, it will mean that people can trade, but it probably means that we will not be able to export for some years - possibly five years - because we would not be able to demonstrate that we have sufficient control over the blood-testing regime," Mr Jones said.

Farmers are expecting a glut of lambs

"If we keep the marts closed for longer, it means that we might be able to export at the end of next year - but, in the meantime, of course, people won't have the income that they would get from normal trading."

Welsh sheep farmers are heavily dependent on exports, and farming unions are already worried about the glut of lambs which will flood the home market later this year.

A delay in reopening the export market is a prospect many will not want to contemplate.

Earlier this year, it was estimated that farmers might not be able to export their animals until Christmas.

Meanwhile, farmers are preparing for a mass meeting on Monday night over fears of a mass cull in Powys - rumours that have been consistently denied by Mr Jones and Wales's Chief Veterinary Officer.
